In recent decades, scholars and policymakers have become increasingly concerned with global patterns of democratic erosion. While political economy literature provides substantial insight into structural determinants of institutional stability, it offers limited tools for identifying when institutional systems approach critical transitions. This paper develops a quantitative framework for detecting early warning signals of institutional phase transitions in democratic regimes. Drawing on complexity science, the study conceptualizes democratic institutions as complex adaptive systems capable of undergoing nonlinear shifts once systemic stress exceeds critical thresholds. Using cross-national panel data covering approximately 120 countries between 1990 and 2025, the study constructs an Institutional Stability Index (ISI) based on governance indicators. The empirical strategy integrates panel econometric models with time-series early warning signal detection techniques. Results indicate that democracies approaching institutional transitions exhibit statistical patterns consistent with critical slowing down. Case studies of Hungary, Turkey, Brazil, and the United States illustrate how these statistical signals appear prior to episodes of democratic backsliding. The findings suggest that democratic erosion follows identifiable dynamic patterns detectable years before institutional breakdown becomes visible
